文中给出了微型红外光源的结构。该光源安装在一个带两根电输出端的晶体管通用壳体内,用两个有弹性的弹簧式夹具把一厚5μm,宽0.75μm、长4mm的尼赫罗姆镍铬合金片固定在壳体内,用有弹性的弹簧式夹具夹住的合金片的应力为合金带断裂应力的15％。壳体顶端有一窗口,窗口上安装有能透过宽红外光谱波段的蓝宝石片或锗片。从壳体内部的背面,在
The paper gives the structure of the miniature infrared light source. The light source is mounted in a common transistor housing with two electrical outputs and a Nihrom nickel-chromium alloy plate with a thickness of 5 μm, a width of 0.75 μm and a length of 4 mm is fixed in the housing by means of two resilient spring clamps, The stress of the alloy sheet sandwiched by the elastic spring-type clamp is 15% of the fracture stress of the alloy band. The top of the case has a window on which is mounted a sapphire plate or germanium plate that transmits the wide infrared spectral band. From the back of the interior of the case, at
